Aiming to strengthen the accessibility of ultrasound technology to rural populations, an advanced strategy ultrasound programme was implemented in the health districts of Sedhiou, Oussouye, Bignona and Ziguinchor all located within Casamance in Senegal. Within the first year of activity (January 1, 2001-December 31, 2001), the team from the regional health centre (RHC) was dispatched 56 times. Ultrasound scans were performed in the homes of 1,273 patients among which 192 were referred to the RHC for specialised follow-up and treatment. The financial benefit for the RHC totaled 3,120,000 francs; 2,612,500 francs for the district hospital; and 3,561,300 francs for the population at large. The advanced strategy for performing ultrasound scans has therefore been economically profitable at the community level as much as at the level of health structures. Through supporting the activities of the district hospitals, the RHC contributed technical support and increased the potential, not solely for the treatment of disease but for the health services overall. The revenue generated has given managers a greater possibility to improve health care and services. The decentralisation programme and reduction in the cost have decreased the unsatisfied needs in ultrasound services by making the technology more financially and geographically accessible. Thus, by saving input costs in terms of time, transportation and capital, the practice of ultrasound scans in district hospitals has been strengthened and has improved the capacity to provide care and treat the population's health problems. The continuation of this programme is advantageous, but necessitates two complementary actions: enhancing of the technical level and capacity of the district hospitals with the installation of ultrasound technology and equipment, and raising the level of knowledge by training staff in administering ultrasound scans.
